A man who had been evicted from a Philadelphia homeless shelter returned on Sunday and opened fire, killing one employee and injuring another, authorities said.

Police said the gunfire occurred at about 6 a.m. inside the Station House Transitional Shelter in north Philadelphia.

The man was evicted Friday night after breaking the rules by being intoxicated, officials said. He returned Sunday morning to get his belongings, but reportedly got into an argument with an employee, pulled out a gun and opened fire.

A man in his 40s was pronounced dead at the scene and a 26-year-old man shot in the hip was taken to a hospital.

Authorities say the gunman was last seen fleeing behind railroad tracks in the rear of the building.
